Processor Sets (Psets) on nPartitions
Procedures for Managing Psets
HP System Partitions Guide: Administration for nPartitions, rev 5.1 430
You cannot modify attributes for Pset ID 0.
/usr/sbin/psrset -t pset_id attr_name = attr_value
where pset_id is the Pset whose attribute(s) will be configured.
Each attribute ( attr_name ) is set to the corresponding value
( attr_value ) specified.
Attributes include OWNID, GRPID, PERM, and others listed in the psrset
(1M) manpage.
/usr/sbin/psrset [-n | -F] pset_id
where pset_id is the Pset for which external I/O interrupts are either
enabled (-n) or disabled (-F).
When configuring attributes other than access permissions, the user
issuing these commands must have write permission for the Psets
specified.
Setting Pset Access Permissions
Step 1. Use the psrset command’s -t option, as described in Configuring Pset
Attribute Values.
To configure access permissions (OWNID, GRPID, PERM), you must have
root or superuser access or membership in a group that has PSET
privileged capabilities.
Specify the PERM attribute and corresponding value to set access
permissions.
/usr/sbin/psrset -t pset_id PERM= p1p2p3
where pset_id is the Pset and p1p2p3 is the set of access permissions for
the Pset owner ( p1 ), Pset group ( p2 ), and others ( p3 ).
Each access permission (owner, group, and others) is a number from 0–7
to indicate execute (x), write (w), and/or read (r) permissions.
0=no permissions, 1=x, 2=w, 3=xw, 4=r, 5=xr, 6=wr, 7=xwr
Execute allows running programs in the Pset, write allows changing the
Pset configuration, and read allows reading the Pset configuration.
